RUC2 FORECASTS

The first plot compares the RUC2 analysis 500 mb
heights from the 12Z RUC2 (blue) to the 12Z Eta (orange);
no major differences are obvious.

12Z 1/24/00 RUC2 vs. ETA 500 mb HEIGHTS

The next 2 plots compare the 12-hour forecasts from
the same 2 cycles. The differences between the 2 models is
greater than at 12Z. The RUC2 is slightly stronger with the
500mb low on the Carolina coast, and the Eta has slightly
higher heights over the Great Lakes and the area from North
Dakota into Canada.
